IMPI-ROVEMENT m SHUTTER-WORKERS.

. The Schedule referred to In these Letters Patent and making part of the same.

I, HENRY H. BARR, of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented an Improved Window-Shutter Operator and Look, of which the following is a specification.

The nature and objects of my invention consist in the arrangement of a gravity trip-lever superimposed on a bent shifting-lever in such manner that both levers and a droppin may be operated instantly with one hand on the insideof the window-sash when it is closed. I

1n the accompanying drawing Figure l-is a top view of the operator as a look.

Figure 2 is a top view of the same as a stop.

Figure 3 is a perspective view of the shitting-lever, trip-lever, and the registered segment.

Figure 4 is a sectional view of rim-socket at the hub of the shifting-lever.

Figure 5 is a, perspective view of the pin employed in the device for stopping the shifting-lever.

Similar letters denote similar parts in the description. 7

W W W is the shifting-lever, arm W having a perforated hooked end, W, through which the guide a b c on the shutter slides,.said guide being supported on the shutter by its returned end I) being driven into the shutter edge on the hinge side, and its other end, 0, screwed or riveted on the inside of the shutter.

Arm W of the shifting-lever is arranged nearly at right angles to arm W, their point of union being a rounded cap or hub, through which a screw, A, passes,

which serves as a center of motion.

The cap A, fig. 4, has a circular r'im underneath, which rides on tlle'outside of a circular rim on the base-plate E, thus forming a journal and bearing for the shifting-lever, so as to relieve the screw A of all duty except to hold the parts at the hub in contact.

ated instantly with one handlwheu the window-sash is closed.

The other end of trip-lever is made heavier, and

has a vertical slot in it to admit the neck of a loose pin, B, fig. 5, as shown in fig. 2, and arm W. of the shifting-lever is perforated to let the pin pass through it and register in the segment beneath it.

The pin, though loose, is irremovable after it is inserted. It is first inserted in the arm W and slot H, and secured in place by afterward securing the triplever in piace by its rivet atT.

' To operate the pin B it is necessary only to trip it and let gravity drop it into any desired hole in the registered segment.

The position of this device is on the window-sill as near as convenient to the jamb, and so far out that screw-head A may be in line withthe inner face of sash-rail, as shown in figs. 1 and 2,

The base-plate is slightly depressed in the sill, so as to let the segment thereon come flush with the sill.

The operations of looking, as shown in fig. 1, when the shutter is closed, fit stopping or holdingthe shutter back, as shown in fig. 2, are effected by trippinghandle D and shifting-handle W To bow the shutter, the handle W is shifted so that the. pin B may register at any desired angle.

I claim- I The combination of the shifting-lever W W W, provided with enlarged hub about the'screw A, with the bifurcated trip-lever H D, and the pin B, when these parts are constructed'as described, and when the handles of the'levers are arranged to facilitate operatin g them in the manner as and for the purpose herein set forth.
